RADIATOR.

SPECIFICATION forming part Of Letters Patent N0. 475,849, dated. May 31,1892.

Application filed June 3, 1891. Serial No. 394,932. (No model.)

.T0 a/ZZ whom t may con/cern:

Be it known that we, ALBERT M. DIMMICK and JESSE T. MORGAN, citizens ofthe United States, residing at Tilkes-Barr, in the county of Luzerne andState of Pennsylvania, have invented a new and usefulRadiator, of whichthe following is a specification.

This invention relates to radiators; and it has for its object toprovide a device of this class which shall be simple and inexpensive inconstruction, and which shall admit of the perfect circulation andheating of the air in the room or apartment where the radiator isplaced, and which shall also admit of cold air being taken from theoutside and heated before it is admitted into the room.

The invention consists in the improved construction, arrangement, andcombination of parts, which will be hereinafter fully described, andparticularly pointed out in the claims.

In the drawings hereto annexed, Figure l is a side elevation of aradiator constructed in accordance with our invention. Fig. 2 is alongitudinal vertical sectional view of the same. Fig. 3 is a verticaltransverse sectional View taken through one of the loops having the feetor supports. Fig. 4 is a perspective detail view of one of the loopsconstituting the body of our improved radiator. Fig 5 is a detailperspective view of one the feet of the device.

Like numerals of reference indicate like parts in all the figures.

Our improved radiator is composed of a series of loops l l, each ofwhich is composed of two vertical pipes 2 2, connected at their upperand lower ends and provided with interior pipes or air-ducts 33,eXtending entirely through the said vertical pipes and open at theirlower and upper ends for the admission and escape of air. The webs orconnections 4 4 at the upper and lower ends of the loops l are providedwith transverse perforations 6 and 7, provided at opposite ends withanges or collars, as 8, and annular recesses, as 9, to receive the angesor collars of the adjacent loops or sections. The transverseperforations or passages 6 and 7 have side openings 10, com municatin gwith the upper and lower ends of the steam-pipes 2. Each of theso-called loops may consist of a single casting or of cast'irou partssuitably fitted together, or it may, if preferred, be constructed ofwroughtiron tubes or pipes suitably connected. Each of the loops isprovided at its 'lower end with a lug 1l, having a recess or perforationl2.

In practice any desired number of the loops l are placed side by side,the flanges 8 of each loop engaging the recesses 9 of the adjacent loop,gaskets or washers being interposed, it' desired, to make steam-tightjoints. A rod 13, screw-threaded at both ends, is passed through thetransverse openings 6 at the upper ends of the several loops and isprovided atits ends with headed nuts 14, whereby the parts are securelyconnected. A similar rod l5 is passed through the perforated lugs at thelower ends of the loops l and is provided at its ends with nuts 16 forthe purpose of securely connecting the lower ends of said loops. Theopenings 7 at the lower ends of the loops at the two ends of theradiator are screw-threaded for the reception of pipes, through whichthe steam is conveyed to and from the radiator. Feet or supports 17 areprovided, having upwardly-extending nipples 1S, adapted to iit in thelower ends of the air-ducts of any one of the loops l. The nipples 18have perforations 19 for the admission of air to the lower ends of theducts 3, in which they are fitted.

The operation and advantages of this invention will be readilyunderstood from the foregoing description taken in connection with thedrawings hereto annexed.

It is obvious that a radiator constructed in accordance with ourinvention may be readily made of any desired length, inasmuch as anydesired number of the loops or sections 1 may be connected by usingconnecting-rods of the proper length. The construction is inexpensive,for the reason that the said loops or sections are all identical inconstruction, and a complete radiator may be constructed of said loopsor sections combined only with the connecting-rods and nuts and the feetor supports whereby the radiator is elevated the desired distance abovethe floor. The individual loops l l are sufficiently spaced to admit ofthe free circulation of air, which may thus be heated by direct contactwith'the exterior surfaces of said loops. Additional heating-surfacesare IOO formed by the airducts 3, which extend through the verticalpipes and which admit cold air at the bottom and discharge it in aheated condition at the top of the radiator.

In Fig. 1 of the drawings we have shown in dotted lines a box or casing21, surrounding the lower end of the radiator. This box or casing is tobe connected by a pipe, as 23, with the exterior atmosphere, and a valveor damper, as 24, may be provided to regulate the admission of cold air.Vhen this construction and arrangement is carried out, pure andnnvitiated air may be admitted from without and caused to pass throughthe vertical heating-pipes 3 before being admitted into the apartmentwhere the radiator is situated. It is obvious that our improved radiatormay be used either with steam or with hot water, as may be desired.

Having th us described our invention, what we claim isl. In a radiator,the combination, with the loops having the vertical steam-pipes and theair-duets extending through said steam-pipes,

of the feet or supports having upward-extending nipples verticallyperforated to engage the lower ends of the air-ducts, substantially asand for the purpose set forth.

2. In a radiator, the combination of the loops having the steam-pipesprovided with interior pipes or air-duets open at their upper and lowerends, and the transverse perforations having side openings communicatingwith said steam-pipes, the vertical air-ducts extending through saidsteam-pipes and having open upper and lower ends, and theconnecting-rods and nuts, and the removable feet fitted in the lowerends of the air-ducts, substantially as set forth.

In testimony that we claim the foregoing as our own we have heretoaffixed our signatures in presence ot' two witnesses.
